Title: Manufacture of semiconductor substrate
Inventor: TAKASU HIROAKI
IPC: H01L21/76
Filed: 1989-11-13
Abstract: PURPOSE:To control the thickness of a single crystal silicon layer low in impurity concentration uniformly below the specified value by forming a single crystal silicon layer low in impurity concentration on a first silicon substrate high in impurity concentration, and specifying the wafer junction temperature. CONSTITUTION:A single crystal silicon layer 2 low in impurity concentration is formed, and the impurity diffusion from a first silicon substrate 1 high in impurity concentration to the single crystal silicon layer 2 low in impurity concentration is suppressed low. Next, a silicon thermal oxide film 3 is formed on the single crystal silicon layer 2 low in impurity concentration, and with the silicon thermal oxide film 3 as the junction face side, the first silicon substrate high in impurity concentration is junctioned with a second silicon substrate 4 at 850 deg.C or less. For this reason, the impurity diffusion during junction is prevented and when etching the first silicon substrate in the subsequent impurity concentration selective etching process, the etching of the single crystal silicon layer 2 low in impurity concentration is prevented. Hereby, the thickness of the single crystal silicon layer 2 low in impurity concentration can be controlled uniformly below the specified value.

Title: Power failure detector
Inventor: KINOSHITA KEIZOU
IPC: H02H3/24
Filed: 1987-11-20
Abstract: PURPOSE:To achieve a higher detection speed in whichever phase a power may fail, by comparing and added value between a squared value of a detection voltage and a squared value of a differential value thereof with a threshold voltage. CONSTITUTION:A detection input voltage of an instantaneous value e=Emsinomegat is inputted into a first multiplier 32 through an input terminal 30 to give a squared value Em<2>=sin2omegat of an input voltage, which is inputted into a second multiplier 42 through a differentiator 34. As the differentiator 34 is set for a product CR1=1/omega of a capacitance C of a capacitor 36 and a resistance value R1 of a feedback resistor 38 composing it, an output of the multiplier 42 gives Em<2>coo<2>omegat. Outputs of the first and second multipliers 32 and 42 are added up to with an adder 46 give Em2, which is compared with a threshold voltage E0 by a comparator 56. Then, when it is below the threshold, power failure is determined to occur. This enables detection of power failure at a high speed in which phase a power may fail.

Abstract: PURPOSE:To pattern a light transmissive film without deteriorating the accuracy and reliability of the pattern by setting the film thickness and extinction coefficient of a carbon film and wavelength of exposing light in a specific relation. CONSTITUTION:After a carbon film 5 and photosensitive resin layer 6 are successively formed on a light transmissive film 4 to be worked, a desired pattern is formed by exposing and developing the layer 6. Then the film 5 is etched by using the formed pattern as a mask and the film 4 is etched by using the layer 6 or film 5 as another mask. At the time of etching the film 4, the film thickness (d) and extinction coefficient (k) of the carbon film 5 and the wavelength lambda of the exposing light are set so that they can satisfy a specific relation, 0.17<=kd/lambda. As a result, the exposing light is sufficiently weakened after passing through the layer 6. Therefore, the intensity of the light reflected by a light reflecting film 3 below the film 4 can be lowered to a sufficiently low level and abnormal exposure of the photosensitive resin layer 6 by the reflected light can be prevented.
